The body block spacers are coming out when the crossmember is swapped out so it'll look a little better after that

The subframe/tranny mount spacers won't lower the car anymore, if that's what you're thinking. Removing them helps correct the geometry of the front suspension. I didn't do it, and my SF is lower than yours. I haven't found any reason to do it yet, car seems to handle fine for a DD. Only reason I would consider doing it is to get more ground clearance for my engine/oil pan for precautionary reasons.
